    for perf record sampling
  perf stat: Fork and launch perf record when perf stat needs to get
    retire latency value for a metric.
  perf stat: Add retire latency values into the expr_parse_ctx to
    prepare for final metric calculation
  perf stat: Create another thread for sample data processing
  perf stat: Add retire latency print functions to print out at the very
    end of print out
  perf vendor events intel: Add MTL metric json files
